This is tricky for me, see I have played two games today, and the last one was Mario Kart DS. Bowser and all the other usual bad guys are in a friendly kart race so, there's not really anyone to be the bad guy.
The other game I played is Evil Genius, where playing the villain is the norm. So this could be interpreted as my being forced to work for the forces of good. Since they are all based on B-movie heroes and spy films from the 60s, this doesn't appeal to me so much. The AI for the common henchman for the villain in the game suggests that lobotomies are mandatory, which is also not a good option. So I would say that I would be find working for the Evil Genius if I got to keep my brain, and be something like a cyborg version of the zombie soldiers that you can make, and also be normal sized so I can fit through the door. That way I don't fall into the traps, can still get a date and can even shoot lasers. I'm pretty sure that would make me better than any henchman in the game, as most only qualify for one of the first two, and no one can claim the last.
Yeah, so, I guess that might be cool. But I still might end up getting stuck in a wall or getting killed by one of the annoyingly invincible super agents.
